Description Majin Sniper 2008-02-26 20:00:20 UTC

Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          GCC 4.1.2 Gentoo eBuild
OS:                Linux

In Kate/Kwrite, when you use the scrollwheel over the scrollbar, only the slider moves, but not the text content. This only applies to the vertical scroll bar, not the horizontal (see Screenshots, the file contains the number 1 to 70, one in each line). I've observed this behavior in Kile as well, so I guess it is a problem in the Kate Part.

This seems not to be a problem with the QT Text Area, since Multiline Edits (e.g. the one on this website to add comments, when viewing the page in Konqueror) do not have this problem.

It's probably in kateviewinternal.cpp. m_lineScroll is of type KateScrollBar. Some signals are connected, but not the signal QScrollBar::valueChanged(int).
I don't have a wheel mouse :o anyone else? :)

The bug 160981 is a duplicate of this.
I can confirm this in KDE 4.1.1 (KDE 4.1.0 (4.1 >= 20080722)) (KDEmod) in ArchLinux i686

Comment 5 Cristi 2008-08-02 08:30:50 UTC

Confirmed with kde 4.2>=20080709 on gentoo

Comment 6 Dario Andres 2008-08-19 18:21:55 UTC

I can also reproduce this using:
Version 4.1.62 (KDE 4.1.62 (KDE 4.2 >= 20080814))
kdelibs4.2 svn rev.849324
kdebase4.2 svn rev.849337
ArchLinux 2.6.25-zen2-20080814 i686

I still have this bug in KDE 4.1.3/Kate 3.1.3
